Pressure Reducing Regulators for Air and inert gases

Pressure Reducing Regulators (PRR) are the most common type of pressure regulator. They reduce an unregulated inlet pressure down to a desired regulated outlet pressure ( learn more).

The manual PRRs listed below are recommended for use as pilot pressure regulators for Equilibar back pressure regulators. All PRRs listed are designed for use with air or inert gas* and have a small but significant weep to the atmosphere.

Contact an application engineer for assistance in selecting the ideal Pressure Reducing Regulator for your application.
